Which term refers to diamond rough with good enough size, shape, clarity, and color to produce a polished stone?

• A. Cuttable rough
• B. Crystalline
• C. Crust
• D. Crystal structure (lattice)

Answer: (A)

The main idea is recognizing when rough diamond has real gem potential. When a piece has enough size, favorable shape, acceptable clarity, and color to yield a polished gemstone, it’s described as cuttable rough. This label distinguishes it from rough that can only be used for industrial purposes or won't yield a marketable gem. The other terms relate to the mineral itself rather than its gem-cut potential: crystalline and crystal structure describe the internal atomic arrangement, while crust refers to the outer rind and isn’t about whether the rough can be cut into a gem. So the best term for rough with the possibility to become a polished stone is cuttable rough.
